Hi guys ...
I give this program show the event number, although previously I had been given but this time in form recursive, because previously I had been given about the iterative ...
ok with it, is how to create a recursive program to call itself, is made using a recursive function and selection, as opposed to just using the iterative looping  ...

So, this is the source code of this program

#include <iostream>
#include<string>


using namespace std;


class angka_genap{
   public:
          angka_genap();
          int genap_rekursif(int i);
   private:
           int i;};
          
angka_genap::angka_genap(){}


int angka_genap::genap_rekursif(int i){
     if (i>20){}
     else{if (i % 2==0) {
         cout << i << endl;      }
     else{}
     genap_rekursif(i+1);
}
}

int main(){
   
     angka_genap x;
     cout<<"\nShow the even number with recursive from 1 till 20\n";
     x.genap_rekursif(1);
   system("pause");
   return 0;
}
